Can't find the perfect name... (F)

So, I'm writing this story about a boy who (to make a very long story short) has to kill his best friend (a girl he has feelings for, however never acted upon those feelings while she was alive) because she got infected with a plague doomed to make her into a zombie. (I don't typically make stories about dystopian zombie infested societies, but sine they're so in now, I figured- why not?)
Anyways, I had initially made this girl's name Lanity. I just made up the name. Chapters into it, I said it aloud. It sounded like manatee...
So I changed it to Verity.
Not cutting it either...
I'd like some help with a name that preferably ends in -ity. It's not necessary, though.

“I read books when I was a kid, lots of books. Books always seemed like magic to me. They took you to the most amazing places. When I got older, I realized I couldn't find books that took me to all the places I wanted to go. To go to those places, I had to write some books myself.”
